TANK DELIVERY STRUCTURE Filed March 20. 1926 2 Sheets-Sheet 2 A TTU/MIEY Patented June 10, 123! UNlTED STATES PATENT OFFICE PAUL S. SHIELD, OFCINCINNATI, OHIO, ASSIGNOR TO AUGUSTINE DAVIS, JR., OF CIN- CINNATI,OHIO TANK DELIVERY STRUCTURE Application filed March 20, 1926.

through a siphon or Siphon-like system.

The purpose of the invention is to provide an especially economical,efficient and reliable construction.

In the accompanying drawings, forming part hereof Fig. 1 is a sideelevation of a tank embodying the invention, an intermediate part ot thetank being broken out because of lack of space;

Fig. 2 is a vertical, transverse section taken in the axial plane of oneof the uptake pipes; and

Fig. 3 is a horizontal cross-section on the line 3-3 of Fig. 2.

rThe tank shown in Fig. 1 comprises a plurality of compartments or tankchambers 2, and at the rear end there may be a box 3, termed abucket-box.

In each chamber there is an uptake pipe LL, having its open lower end ina bottom pocket 5, and stayed at the toot by a suitable spider 6.

The pipe 4 passes upward through the bottom of a box 7 ot largerdiameter, thc upper end of the pipe terminating in this box, which issecured in a flanged opening 8 in the top et the tank shell. The bodyoit this box is advantageously made of a tubular piece 9, consisting ofa short length of large pipe. rlhe side or this member is welded to theshell at 10, with a portion ot' the member projecting above the shell;and in the lower end of the member an annular pipe 11 is welded, formingthe bottom of the box. The pipe 4 is secured by welding in the openingof the bottom piece.

An opening 12 is formed in the tubular piece 11, adjacent the bottom,and at this opening is welded or otherwise secured an outlet pipe 13,which is shown extending downward within the tank to join a manifold 14,said manifold passing to the rear through the wall oi the tank chambers,and terminating at the bucket-box in a suitably Serial No. 96,236.

valved outlet 15 adapted to receive a delivery hose.

-A flanged thimble 16 having a horizontal top flange 17 is telescopedover the projecting upper end of the tubular piece 9 and there welded,the thimble thus forming part of the box heretofore referred to.

The upper end of the uptake pipe fl is screw-threaded, and screwed onthis portion is a valve-seat ring 18. The valve-seat, and the upper endot the pipe, are accurately centered and braced in the box by a spider19, the arms of which extend from an upper ring 20 downward to the ring18, being integral with both. The ring 2() closely fits the interior ofthe thimble, and by resting on a shoulder 21 in this thimble affords anadditional, suspensional support for the uptake pipe, taking part of thestresses oil: jolting, etc. from the welds which unite the pipe 4 withthe lower end of the box, and more directly taking the shock ot thespring closing of the valve on the seat.

A cover 22 is removably applied to the thimble 16, being tightly boltedto the flange 17 by screws 23. A downwardly projecting circular rib 2-1-on this cover enables it to be centered accurately on the thimblc, fromwhich, in turn, the valve-seat 1S is centered.

The cover 22 has a stutling-box 25 and a downwardly projecting guidebearing 2G, for the stem 27 of' a poppct valve 2S, which seatsdownwardly on the valve-seat under the action of a spring 29.

The protruding upper end` of said valvestem is arranged to be acted uponby one arm ot a bell-crank rocker 30, which is pivoted in asuperstructln'e 3l on the cover. An operating or control mechanism ofthe kind disclosed in my copending application filed of even dateherewith, Serial No. 96,- 235 is illustrated. T his mechanism need notbe specifically described here; but it may be stated that the rockers 30are actuated through levers 32 to lift the valves, said levers beingoperatable by dogs 33 on a common turnable and longitudinally movablecontrol rod 34.

Vhile the preferred embodiment of the invention has been described indetail, it will be understood that I do not wish to limit myself to theprecise form, since vari-` ous changes may be made Within the scope ofthe claims.

I claim:

l. In a tank, siphon means for emptying the tank comprising a boxsecured in the top of the tank, and an uptake pipe and an outlet pipecommunicating with the interior of said box, one of said pipes beingunited to said box and projecting upward in the interior thereof, avalve-seat applied to the upper end of this pipe, and a single spiderpositioning said valve seat in the Y box and bracing` the upper end ofsaid pipe.

2. In a tank, siphon means for emptying the tank comprising a boxsecured in the top of the tank, and an uptake pipe and an outlet pipecommunicating with the interior of said box, one of said pipesbeingunited to said box and projecting upward in the interior thereof,and a spider member having two rings, one iitting the interior of thebox and the other being a valve-seat which is applied to the upper endof said'pipe.

3. In a tank, siphon means for emptying the tank comprising a boxsecured in an opening in the top of the tank, and an uptake pipe and anoutletvpipe communicating with the interior of said box, one of saidpipes passing upwardly within said box member and secured to the bottomthereof, a thimble secured on the upper end of said box member outsideof the tank, a valveseat applied to the upper end of said pipe, with aspider centering said valve-seat aiiid bracing the upper end of saidpipe from said thimble, a cover for said thimble7 and a valve carried bysaid cover to coact with said valve-seat.

L In a tank, Siphon means for emptying the tankoomprising a box securedin the top of the tank, and an uptake pipe and an outlet pipecommunicating with the interior of said box, one of said pipes passingthrough and being united to the wall of said box and being provided atits upper end with a valve seat, supporting means seated in the box andengaging the upper portion of said pipe, and a valve guided in the boxto close against the valve seat at the upper end of said pipe.

In a Itank, siphon means for emptying the tank comprising a box securedin the top of the tank, and an uptake pipe and an outlet pipecommunicating with the interior of said box, one of said pipes passingthrough and being united to the wall of said box, and centering andsupporting means having a portion fitting and seated in said box and aportion engaging the end of said pipe and affording a valve-seat.
